A little experience with film cameras but pick things up straight away so even with a pro camera I will eventually work out the system.

Basically I would like your opinion on which camera set I should get and why?

The one that costs the least. Why? So you can get a nice lens, a flash, a tripod, a camera bag, cleaning kit, an extra battery, a memory card, and all the other little things that go along with a new camera system.

If you really can figure things out quickly, then you will be able to produce more, with less. Good luck.
